"PHEW is a Mt. Airy based full-service bicycle shop that sells an array of regular, folding and electric bicycles throughout the tri-state region. The shop does repairs as well as offers bicycle renting service for approximately $50 per day. The store also sells conversion kits, which gives bicyclists the option to convert their own bicycle into an electric-assisted bicycle, which is perfect for those that have special needs."
